How are you planning to capacity test?
Put them in 16s, draw them down to 3.1 or so volts while watching carefully.
Put them in 16p, stick them on my powerlab8 in discharge mode, discharge to 2.90V. Let them rest. Discharge again. Let them rest again.
Now they are bottom-balanced, but you could do the same thing except in reverse and top-balance. (And you probably should, especially if you are using a balancing BMS.)
Put them back in 16s, charge them up while counting energy in, and watch the voltages. If any go wild too early, I have a weak cell that might need replacement. Otherwise, if they get to 100% of rated or better, call it a day.
It's easier to do some of those things with the help of an inverter/charge and a dedicated 3V battery tool (powerlab8). Also, I practiced in the past.
Yep, sounds like you have way more experience than me - this is my first pack - I think I'll just buy the $250 48v AIMS inverter to test with and then sell it on Craigslist once I'm done -I've posted at link below what my plan is for capacity testing:
mine got to door 6 weeks after going to bankSo i am on day 35 now of waiting for my 280aH Xuba batteries to even reach FEDEX in the States ... my two other orders from 2 other companies have already been here for two weeks and already installed.
My question is - how long are your guys XUBA batteries taking ???
Ordered 8 more cells from Amy and she shipped them Aug 6th. Just got my fedex notice that they will be here the 8th. 32 days makes me wonder if they went by sea or not.

Sorry to revive old thread but I get the idea that ordering in the next 30-45 days might not be a good idea due to Chinese New Year disruption.
Since this would be my first buy (~16 280ah) Im trying not to make a huge noob mistake.
Also, is there a thread for group buys ?
